Selena Gomez Is Still A Belieber!!!

Justin Bieber had a special guest at his Wednesday L.A. concert ... ex-girlfriend Selena Gomez.

Looks like she got one of the best seats in the house too.

Justin's been linked to several other people since they broke up but he's no stranger to serenading her ... and just a few days ago he posted a throwback picture of them kissing.

Is it too late to say Jelena?
